The phospho-ERK1/2 (Thr202/Tyr204), ERK1/2, phospho-AKT (Ser473), AKT, phospho-EGFR (Tyr1068) phosphor-mTOR (Ser2248) antibodies were from Cell Signaling (Danvers, MA); EGFR antibody was from Abcam (Cambridge, MA). MGL antibody was generated in our laboratory as previously described6 (link). The β-actin and α-tubulin antibodies were from Sigma (St. Louis, MO). GAPDH, vinculin, TNF-α and COX-2 antibodies were from Santa Cruz Biotechnologies (Dallas, TX). pDsRedN1-MGL vector (MGL-RFP) has been previously described6 (link). For pSRα-HA-S-tagged MGL expression vector, complete human MGL ORF was subcloned into mammalian pSRα-HA-S vector (contains HA and S tags) and DNA sequencing was performed to confirm the integrity of MGL sequence.
